- MrMax99, on 04/01/2008, -5/+227OH NO! I should have read the description. My pets and younger siblings are making crop circles and going deaf.
- noseeme, on 04/01/2008, -3/+114Rice is better at math than I am.
- davidlow, on 04/01/2008, -5/+102I'm a meat and potatoes guy. Will this work with potatoes instead of rice? Potatoes resonate much better with me.
- 3F05Q, on 04/01/2008, -0/+55"WARNING! This video contains ultra-sound frequencies that may be harmful for your pets or young family members!"
Not so much. Even if youtube was streaming a sample rate of 44.1khz (CD sampling rate), which it isn't, then the maximum frequency would be 22.05khz. - Wilson, on 04/01/2008, -3/+37I'm assuming it would start to never give us up.
- bossm4n, on 04/01/2008, -2/+35Reminds me of the Rubens' Tube experiment. http://www.youtube.com/watch?v=HpovwbPGEoo
- CTK14A, on 04/01/2008, -1/+31Uhh… It’s probably not a problem… probably… but I’m showing a small discrepancy… well, no, it’s well within acceptable bounds again. Sustaining sequence.
- Percele, on 04/01/2008, -0/+30They're waiting for you, Gordon, in the test chamber...
- inactive, on 04/01/2008, -2/+30What explains all the crop cricles are people with rope and boards.
- hypodan, on 04/01/2008, -1/+28That's what she said.
- BlackOp, on 04/01/2008, -0/+26Youtube videos cannot contain ultrasound frequencies. And nobodies speakers/sound system would reproduce them anyway.
- Mydnyte, on 04/01/2008, -0/+23Just to clarify, the effect has nothing to do with the rice itself. You can use sugar, salt, or any other small-grained substance you can come up with. You are seeing standing waves in the sheet metal, made visible by the rice.
- felidaeus, on 04/01/2008, -0/+18I'm worse off. Rice is better at football than me.
- FoxOrian, on 04/01/2008, -1/+19Lose control of your bowels, I'm guessing.
- Enderplayer1, on 04/01/2008, -1/+18my dog hates you
- madcat033, on 04/01/2008, -2/+16My member was unharmed by these frequencies.
- h4mx0r, on 04/01/2008, -0/+13that's what I was thinking. I mean, not that specifically, but I was thinking more along the lines of compression and audio quality
- multifingered, on 04/01/2008, -3/+14I bet that would be cool to sit on.
- blahtastic, on 04/01/2008, -0/+11We used sand when we did it in High School a couple years back. Then again, we didn't have an awesome speaker to make the sound either.
Had to rub a violin bow on the side of the thing to get it to resonate.
And walk a mile uphill both ways every day to get to school.
In the snow.
With a sasquatch on the loose.
Now all you kids got it easy, just have to watch out for red haired 80's pop crooners popping up every so often. - trenchfever, on 04/01/2008, -1/+11Indians draw such images. They say that it resonates with the sound of nature.
http://images.google.com/images?q=rangoli - 4rp4n3t, on 04/01/2008, -0/+9Because the rice would just sink to the bottom and stay there. Ultrasound is much more interesting...
- BigLLamasHouse, on 04/01/2008, -0/+9such as the iraq, and such as...
- HydrogenY, on 04/01/2008, -1/+10The lady diggers were wondering about sitting on it.
- pantsydecision, on 04/01/2008, -0/+9from wikipedia:
Resonance occurs widely in nature, and is exploited in many man-made devices. Many sounds we hear, such as when hard objects of metal, glass, or wood are struck, are caused by brief resonant vibrations in the object. Light and other short wavelength electromagnetic radiation is produced by resonance on an atomic scale, such as electrons in atoms. Other examples are:
acoustic resonances of musical instruments and our vocal cords
the oscillations of the balance wheel in a mechanical watch
the tidal resonance of the Bay of Fundy
orbital resonance as exemplified by some moons of the solar system's gas giants
the resonance of the basilar membrane in the cochlea of the ear, which enables people to distinguish different frequencies or tones in the sounds they hear.
electrical resonance of tuned circuits in radios that allow individual stations to be picked up
creation of coherent light by optical resonance in a laser cavity
the shattering of crystal glasses when exposed to a musical tone of the right pitch (its resonance frequency). - seans9, on 04/01/2008, -2/+10Creepy
- BigLLamasHouse, on 04/01/2008, -0/+8cue foghorn of failure
- jerryterhorst, on 04/01/2008, -0/+8or the most popular video game in the last decade
or that - omnithought, on 04/01/2008, -0/+8I think my brain just turned into a kaleidoscope
- Scynet, on 04/01/2008, -0/+7Use what? Resonance? I can assure you that the idea of resonance is present in a lot more things than you'd think.
- robeph, on 04/01/2008, -0/+7Because water doesn't hold its form in a standing wave, it kinda sloshes around =...not quite the same effect.
- pantsydecision, on 04/01/2008, -0/+7so all you have to do to create crop circles is blast ultra-sound frequencies from a hover craft at a field of corn?
- Tyorant, on 04/01/2008, -0/+7Gordon! Get away from the rice! It's not shutting down..its.AGHHHHHH
*Rice everywhere* - keyme, on 04/01/2008, -0/+6Interesting. Looks like the sound waves reflect off the edges of the board, and create an interference pattern. The rice is probably concentrated on the lines where the waves cancel each other out, because these are the lines where the board vibrates very little.
On the other hand, I'm no mathematician, so I'd like to see a real explanation. - 4rp4n3t, on 04/01/2008, -0/+6That's just old age catching up woth you Habemus
- B3000, on 04/01/2008, -2/+8Very cool, but it needs a stronger warning. My windows just broke and i think i may have crapped myself.
- evildaz, on 04/01/2008, -0/+6Has anybody tried this with Anneka Rice??
- smacksaw, on 04/01/2008, -0/+6No, just your hearing. Every time it changes, they amplify it. You should be able to hear it then, I'd hope!
- lovecss, on 04/01/2008, -0/+5Dugg for "Foghorn of failure".
- kaph, on 04/01/2008, -2/+7Actually it was more than a month.... but who cares? I knew what it was as soon as I saw the pic (you should have as well since you are so attentive...). It didn't stop me from watching it again and enjoying it (my cat didn't though). Add to that the amount of diggs this has is the roughly minimum amount of people who missed it last time.
- inactive, on 04/01/2008, -4/+9Mythbusters is wrong. I experimented with this in a lab at a division of CBS Musical Instruments decades ago using high-powered amplifiers and bass speakers. I was able to resonate body organs - it's a *very* weird feeling - and found you can put enough acoustic power into the rectum to vibrate the muscles loose. There is no single 'brown note' but down in the subaudio range you CAN affect various people this way. It takes at least 50 acoustic watts (which is mechanical power, not the electrical power value). I stopped experiments because of the danger of damage to tissue and organs.
- 4rp4n3t, on 04/01/2008, -0/+5I'm guessing the sound at the end was the experimenter's brain squirting out of their ears...
- Uberwon, on 04/01/2008, -0/+5it is salt
- darlingt, on 04/01/2008, -0/+4Failure. It's uuiU.
- FizzanoMatrix, on 04/01/2008, -3/+7That is the most ***** awesome thing I've ever seen.
- feanix, on 04/01/2008, -0/+4This would make a cool feature for a first contact style movie. Aliens somehow use sounds to make weird shapes on earth. Imagine one of those shapes spanning the sahara.
- Mike89, on 04/01/2008, -1/+5If he's got more than one bowel he has bigger issues on his hands.
- rompom7, on 04/01/2008, -0/+4Hmm first time I saw this video a long time ago, the description said it was salt, not rice.
- Abomonog, on 04/01/2008, -0/+4You'll need a lot more volume. But theoretically you could do it with any solid object(s).
And that is an incredibly bad pun. :) - arizonagroove, on 04/01/2008, -0/+4"This effect might explain some famous crop circles."
Either that or crop circles are man made and were originally thought up by English two blokes in a pub in 1976 who though it would be funny.
http://en.wikipedia.org/wiki/Crop_circle
http://www.circlemakers.org/ - Abomonog, on 04/01/2008, -0/+3It means that it was the American Indian that invented and perfected the Spyro Gyro childs drawing toy and Mattel needs to get slapped with a lawsuit. :)
